You can try to post this on the Mac forum as this is the Windows PC forum. They'll know more about your situation there. My best guess is that you are experiencing what we all refer to the power harness problem. It is a well know problem for Digi002 and Digi002R interfaces. In the short term you need to open up the unit and reseat the power harness connections (The thick wires). In the long term, you should get a new power harness from Digidesign and replace the existing one. Hope this helps.
